Hey all, we here at True Shot Academy are going to talk about H&K today. The company is well-known for their wide variety of products which have been used by armed professionals, recreational shooters, and concealed carriers alike. Our goal with this blog post is to provide a brief overview of H&K while delving into things such as their history, traits, product offerings, and more. Without further ado, let’s talk about H&K.


Who is H&K?

H&K, formally Heckler & Koch, is an iconic firearm manufacturer based in Obendorf, Germany. The company is approaching its 75th anniversary as it was founded on December 28, 1949. Founded by ex-Mauser engineers, the company initially produced a variety of goods such as tools, sewing machine and bicycle parts, gauges, and more. The company pivoted to firearms production in response to a Bundeswehr service rifle contract in 1956. H&K responded to this solicitation and produced the rifle that would ultimately become the G3 service rifle. The rifle fired the 7.62x51mm NATO cartridge and utilized a unique roller delayed blowback system. After the G3 was adopted in 1959, the company shifted its main focus to defense industry production.

H&K would go on to design and produce a wide variety of firearms from the 20th century to the present day. 1969 and 1971 saw the addition of two more iconic firearms to the roller locked family which followed in the footsteps of the G3, the MP5 and HK33. The MP5 is an iconic submachine gun in 9mm Luger which spawned a number of variants such as the MP5K and MP5SD. The HK33 rifle was essentially a scaled down G3 chambered in 5.56x45mm NATO. These firearms in addition to the G3 were some of H&Ks most prominent designs during the Cold War era. Additionally, the company was also the first to produce a polymer-framed handgun in the form of the VP-70 pistol. After this initial design, polymer-framed handguns became the subject of focus for H&K, leading to the development of many designs throughout the 20th and 21st century. During the late 1980’s, H&K developed the designs which would eventually become the Mk23 and USP line of handguns.

Beyond the Cold War era, the company has also notably developed their 416 and 417 lines of rifles. These rifles bridged the gap between M4/M16 platforms and piston driven systems and have been employed by numerous law enforcement and military entities. Other notable designs in the 21st century have included the G36, UMP-45, and the many new handgun offerings such as the HK-45 and P30 lines. In the modern era, H&K is still trusted by armed professionals and citizens across the globe. Their offerings may demand a high cost, but they are of high quality and will not light you down.

Pistol Offerings

Some of the most common H&K firearms you will encounter will be of the pistol variety. These handguns are available in a variety of forms and sizes. The main two methods of operation supported by H&K when it comes to traditional handguns are double action and striker fired handguns. The hammer fired pistols offered by H&K come in a number of variations, allowing users to find a system which best fits their needs. Some offerings include manual safeties and decockers while others omit them or have one over the other. At this point in time, a majority of the firearms produced by H&K for commercial sales are going to be handguns.


Popular H&K handgun designs include:

  • USP Series – Available in 9mm Luger, .40 Smith & Wesson, and .45 ACP. Also available in full-sized and compact variants. Additionally, these pistols can be acquired in a number of DA/SA variations (safety/decocker, decock only, LEM style, etc.). Can be acquired in the form of Expert and Elite models which feature match triggers and longer barrels. Can also be acquired in the form of Tactical models which have threaded barrels and suppressor height sights.
  • P30 Series – Available in 9mm Luger and .40 Smith & Wesson. Available in long slide, full-sized, and compact variants. Additionally, these pistols can be acquired in a number of DA/SA variations (safety/decocker, decock only, LEM style, etc.).
  • HK45 – Available in .45 ACP. Also available in full-sized and compact variants. Additionally, these pistols can be acquired in a number of DA/SA variations (safety/decocker, decock only, LEM style, etc.). Can also be acquired in the form of Tactical models which have threaded barrels and suppressor height sights.
  • VP Series – Available in 9mm Luger and .40 Smith & Wesson in the form of the VP-9 and VP-40 respectively. Also available in full-sized and compact variants. Can also be acquired in the form of Tactical models which have threaded barrels and suppressor height sights. Additionally, some VP models can be had in Optics Ready configurations.


Beyond traditional handgun offerings, the company also offers their SP5 product line. These offerings are essentially commercialized versions of their MP5 submachine gun, available in a full-size and “K” configuration. These pistols are essentially modern production offerings of their older HK-94 offerings from a few decades ago.


Rifle Offerings

Beyond their pistol offerings, H&K produces a variety of rifles. These rifles include their MR556 and MR762 product lines, offering customers commercial versions of their iconic 416 and 417 rifles used by militaries across the globe. The MR556 rifles are chambered in 5.56x45mm NATO while the MR762 rifles are chambered in .308 Winchester. Additionally, the company also offers their SL8 and USC offerings, in 5.56 NATO and .45 ACP alike. These offerings serve as commercial analogues the G36 and UMP-45 firearms respectively. Additionally, the company also offers .22 Long Rifle chambered variants of their 416 and MP5 in the form of rimfire rifles.


Option To Convert Rifles

While H&K offers their SL8 and USC carbines, many shooters wish they do not exactly scratch the itch many shooters have for some of their more exotic carbine and subgun offerings. Specifically, the SL8 and USC carbines can be sent off to Tommy Built Tactical to be converted to a more appealing form. SL8s tend to be turned into rifles resembling H&K G36 style rifles and H&K XM8 rifles. As far as the USC goes, these can be converted to resemble the iconic H&K UMP-45 submachine gun.

The conversion process is much more than a simple aesthetic upgrade and parts swap. Additional functionality is provided by a Tommy Built Tactical conversion. One of the most notable benefits of a conversion is the fact that the firearms will now be capable of accepting double stack magazines. In their imported form, SL8 rifles and USC carbines ship with single stack magazines. This is due to import laws which require imported firearms to be of the “sporting” variety. Additionally, the process also removes the bulky thumbhole stocks from the firearms, yielding pistol grips and traditional stock options to the shooter.


Suppressor Ready Offerings

In H&K nomenclature, the term “Tactical” is often applied to pistols offered with threaded barrels. These threaded barrels allow the user to affix a sound suppressor or other muzzle device to their handgun. These threaded barrels will generally feature metric thread patterns of the left-handed variety. 9mm Luger offerings are typically going to feature 13.5×1 LH threading while most .45 ACP offerings will feature 16×1 LH offerings. The Mk23 pistol from H&K departs from this tradition and has a right-hand threading in the form of a 16×1 RH thread pitch. These offerings will also generally feature recoil spring assemblies which are an optimal weight for use with suppression.

Military Contracts

In addition to their use by law enforcement, H&K products have been employed by numerous military entities across the globe. In addition to H&K produced firearms being utilized by militaries, a number of licensed clones and reproductions have also been utilized. Notably, MKE in Turkey was officially given license to produce HK pattern firearms such as the MP5, G3, and HK-33. These firearms and others have been utilized for military purposes.



All in all, H&K is a company which has persisted for nearly 75 years, and for good reason. Their offerings have set standards for battle rifles, subguns, handguns, especially when it comes to suppression and tactical weaponry.
